Hmmm, this doesn't look right:

Seems as if the leaf spring has twisted from its correct position? The other side is slightly distorted in the other direction, but not as badly.

Looking at the parts book drawings, I'm having some difficulty seeing how the leaf spring is supposed to be located ... any hints and tips?

Thanks,

Peter

I don't know if you are looking for this.

I choose this configuration for my rally car and I can say that sometimes I'm happy sometimes not.
For tarmac and track use is ok. Is the only way to get -1,3 camber without changing the wishbones, but the teflon material should be special for high temperatures.
There are many strange noises and the front suspension became very tight. The steering wheel became very sensitive and reads everything on the road. It's good but isn't frently for long races. I thing I'm going back to the factory conf, looking for a 1st series subframe to modify the front of the car.

Christos, thanks for replying to a *very* old post! Actually, I think I was using the wrong term when I said 'silentbloc' ... I was actually talking about the rubber connection between the top of the upper A-arm and the end of the transverse spring.

I've heard that it's not unusual for that part to be offset as shown in my pictures. No-one seems to know why. Since then I have repositioned the spring, which reduced the offset quite a bit.

Moving on ...

Your off-center bushings are interesting. Also your report on how they feel on the road. Presumably you get more steering kick-back because the steering axis no longer goes through the tire contact patch? I've often wondered how the rally cars with zero or negative camber would feel.
